1st Post，感谢社区。如果它更适合在另一个论坛道歉
我正在运行Ubuntu 12.04 LTS服务器作为我的主机。
/etc/libvirt#kvm——版本
QEMU模拟器1.0版（QEMU-kmm-1.0），版权所有（c）2003-2008 Fabrice Bellard
我构建了一个运行Ubuntu 13.10的虚拟机。当我进入XML为静态IP配置以太网tap0接口时，我遇到了麻烦。我翻遍了网，试了好几种方法，都没有用。
这是我得到的错误
错误下面是我的配置和日志
下面是我尝试过但没有成功的事情清单。。。
-#virsh启动phabVM错误：无法启动域phabVM错误：内部错误读取控制台日志输出时进程退出：char设备重定向到/dev/pts/1kvm:-netdev-tap，ifname=tap0，id=hostnet0:无法打开/dev/net/tun:不允许操作kvm:-netdev-tap，ifname=tap0，id=hostnet0:无法初始化设备"tap"

我（从互联网研究中）尝试过的事情都没有奏效
已将用户添加到组kvm
配置libvirtd.conf并取消注释listen_tls和listen_tcp
通过将root设置为运行VM的用户/组来配置qemu.conf；未注释的
clear_emulator_capabilities=0
残疾人服装
确保kvm二进制设置为kvm组
尽量不要使用<interface type="ethernet">，对于更安全、更易于管理的网络接口，还有很多不同的可能性。如果您确实需要使用以太网类型的接口，那么您可以按照libvirt wiki页面了解这个问题，但我必须强调，我不建议这样做。
